Specification of Letters Patent.

Patented Apr. 13. 1920.

Application filed March 5. 1919. Serial No. 280.792.

To (1M whom it may eom'em lie it known that I. lll'lltMAN' Nonniulpt. a citizen of the I nited States. residing at San Pedro. in the county of Los Angele and State of California, have invented new and useful Improvements in Airships. of which the following is a speeitieation.

y invention relates to ail-ships and eonsists of the novel features herein shown. described and elaimed.

Figurel is a perspeetire of an airship embodying the prineiples of my invention.

Fig. 2 is a sectional elevation.

Fig. 3 is a fragmentarw horizontal seetion on the line 3 3 of Fig. 2.

The airship ear 1 is espeeialtr intended for carrying passengers. A lower front lift ing plane 2 extends from the right-hand side and bottom of the car. A second lower front lifting plane 3 extends from the lefthand side and bottom of the car. The upper front lifting plane. 4 is mounted above the. lower plane 2. and the upper front lifting plane 5 is mounted above the lower plane 3. In a like manner the lower rear lifting plane (i extends from the right-hand side and bottom of the rear end of the ear. the lower rear lifting plane T extends from the left-hand side and bottom of the rear end of the ear. and the upper plane a is mounted abore the plane ti. and the upper plane 9 i mounted above the plane 7. thus making a double biplane airship.

A propeller 10 is mounted between the planes 2 and l, a propeller 11 is mounted between the planes 3 and 5. a propeller 12 is mounted between the planes (1 and 8. and a propeller 13 is mounted between the planes 7 and 9. The propellers 10, 11. 12 and 13 are adapted to be controlled independently and to pull forwardly and backwardly as desired. Pivot posts 14 and 15 extend up wardly from near the front end of the top 16 of the car 1. the lower ends of the osts being rigidly mounted on the top an the upper ends of the posts being so ported by braces 17, 18, 19, 20., 21, 22 an 23. The stabilizing blades 24 and 25 are pivotally mounted upon the osts 14 and 15, said blades being norma ly in planes parallel with the axis of the car 1. In a like manner the pivot posts 26 and 27 extend upwardly from near the rear end of the top 16 of the ear 1, the lower endsfof the posts being fixed upon the top and the upper ends being supported by braces 28, 29, 30, 31, 32," 33 and the blades 35 and it 34. The stabilizing blades 55 and 3t) are pirotallr mounted upon the [)(lsts 21' and '37. said blades being normally in line with the blades 24 and 25. rod 37 connects the forward ends of the blades 24 and 25. and a similar rod 38 eonneets the forward ends of eord iltl is eonneeted to the renter of the rod lla and e.\- tends around a guide pulley ill and forwardly around a guide pulley ll and is rolr lltt'tttl to the renter of the rod ill. similar (-ord 12 is ronneeted to the center of the rod 2% and extends around a guide puller l?) and forwardly around a guide puller H and is eonnet'ted to the renter of the rod 57. A we hle i5 is connected to the renter of the rod 37 and extends over a guide pulley lb and downwardly through the top 16 under a guide pulley 47 around the tiller pulley 4* baekwardly under a seeond guide pulley similar to the guide pulley 4T upwardly through the top 16 over a guide pulle i l and to the point of starting. so that when the tiller wheel 50 is operated the eable 4.) will be operated to swing the stabilizing blades 24. 25. 35 and 36 upon the pivots 14. 15. E20 and 27 as desired to stabilize the air ship. The tiller wheels .31 and 52 eontrol the rudders and tail pieces 5:).

Thus I have produeed an airship having a long" ear adapted for earrying passengers and having lifting planes extending from near its forward end. and lifting planes extending from near its rear end. so as to balance the ear forwardlv and baekwardly.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. An airship including a ear. upper and lower lifting planes extending from both sides of said ear near the forward end thereof. upper and lower lifting planes extending from both sides of said ear near the rear end thereof. vertical and horizontal rudders at the rear end of said ear. propellers mounted at both sides of said car forwardly and between said forward upper and lower planes. propellers mounted at both sides of said oar rearwardly and between said rear upper and lower planes, a air of vertical longitudinal stabilizing bla es mounted on top of said car between the forward upper planes and the rear upper planes respectively. and means for turning said stabilizing blades.
